Grumpy Cat Brings a Thousand Fans to Changing Hands in Tempe

The Valley's Tardar Sauce (a.k.a. Grumpy Cat) at Changing Hands Bookstore in Tempe on Sunday. See more photos of her appearance via our slideshow.

Grumpy Cat, the most famous feline in the Valley -- if not the entire Internet, made its first-ever public appearance on Sunday afternoon at Changing Hands Bookstore in Tempe and more than a few fans were there for the occasion. Employees at the store estimate that more than a thousand people waited in line for several hours for the chance to get their photograph with the local Internet sensation, whose real name is Tardar Sauce.

People came sporting Grumpy Cat T-shirts, clutching hand-drawn pictures of the local kitty, and ready to do their impression of the cat's famous scowl. They stood in line patiently for their 30 seconds of interaction with Tardar Sauce and her owner Tabatha Bundesen.
